A new liner, a floating cover, and a wildfire: Reviving the Wrigley Reservoir on Catalina Island

The Wrigley Reservoir is the main treated-water reservoir on Santa Catalina Island, California. Located on the mountain above the town of Avalon, the reservoir provides potable water to the town and other parts of the island. Two interesting aspects about the fabrication process stood out. The first was that 3-in.-wide welds were used for all welding on these panels. The 3-in.-wide weld extended to the edge of the top panel, effectively welding down the edge and eliminating a flap on the surface. The roads through the town and up the steep mountain required a truck trailer no longer than 40ft. Most truck trailers today are 45ft or longer and it took a while to find shorter trailers to rent.
